adductor muscle of carapace
- Muscle attached to carapace for pulling it to the body (thorax) or connecting halves of bivalve shell (e.g. Conchostraca, Ostracoda, Leptostraca) or valves of cirriped capitulum for closure of them. In Cirripedia, any transverse muscles, particularly that of maxillary segment, for closure of aperture; in Thoracica, adductor (adductor scutorum) acts upon scutal plates or valves [Moore and McCormick, 1969].(Order Diplostraca):Well-developed muscle attaching each side of head region to carapace. (See also ligament) [Stachowitsch, 1992].(Order Leptostraca):Carapace adductor muscle [Stachowitsch, 1992].(Subclass Cirripedia):Conspicuous transverse muscle joining both scuta and serving to close aperture [Stachowitsch, 1992].(Subclass Cirripedia):Muscle attached to carapace for pulling it to body or connecting halves of bivalve carapace [McLaughlin, 1980].(Class Ostracoda):Well-developed transverse muscle extending from body to inner surface of each valve. Forms characteristic muscle scars on valves and serves to close carapace [Stachowitsch, 1992].
